Tango Palace is one of the very, very few indie coffee shops in Toronto that actually opens late in the night. A blessing when you or a friend want to hang out and get some stuff done and it's long past 1800h.
The atmosphere is cozy and baristas are friendly. A variety of grub to go with decent drinks. Great music that should be enough to get those damn earphones out of your ears. Or just head to the very back, where you'll find a giant patio, where they will also regularly host musical events.
Also, gotta love the espresso machine they got--a friend remarked it was like a golden steampunk R2D2.
